Consider the following torsion problem. The shaft is 2 m long with a linearly tapered radius that varies from 3 cm at the wall to 1 cm at the free end. It is subjected to a uniform distributed torque t = 15 kN-m/m. Take G = 80 GPa. Calculate the total twist angle of the shaft. Calculate the end torque that would be required to make the total twist angle zero. Suppose the shaft is fixed at both 0 and 2 m. Calculate the reaction torques at the two walls.
The answer of the following questions are as follows
a) The total twist angle of the shaft is 15 degree.
b)The end torque that would be required to make the total twist angle zero is 1700 N-m.
